Background
The conventional electrodeposition of zinc hydrometallurgy enterprises maintains the manganese balance of the system, but because the manganese content in the system is continuously accumulated and exceeds the normal production allowable value due to improper operation of the zinc smelting raw materials, other methods are required to be adopted to remove manganese from the zinc hydrometallurgy system, the main method at present is a reagent oxidation method, and impurity ions which are seriously harmful to zinc production are generally introduced, and the reagent is expensive, high in consumption and high in production cost.
Iron, particularly ferrous ions, in zinc hydrometallurgy systems also have a significant impact on production, and for iron removal, it is generally necessary to oxidize the ferrous ions, and the common oxidant for iron removal in the neutral leaching process or in the hot acid leaching solution is MnO 2 、O 2 、H 2 O 2 For example, H is commonly used for deeply purifying and removing iron in iron-containing solutions such as supernatant liquid of medium leaching 2 O 2 As an oxidizing agent. The reagent oxidizes ferrous ions and subsequently removes iron, and the recognized defects are low efficiency and high production cost.
The hazard of chlorine in a zinc hydrometallurgy system is also larger, so that the cathode and anode plates can be corroded, the service life of the cathode and anode plates is shortened, the lead content in the electrolyte is increased, and the quality of the cathode zinc sheet is directly affected.
Aiming at the problems, a diaphragm electrolysis mode is adopted to purify and remove manganese, iron, chlorine and the like in a zinc hydrometallurgy system. The traditional diaphragm electrolysis in the technical field of wet metallurgy is to put a polar plate into a diaphragm bag, wherein the anode diaphragm method is to put an anode into the diaphragm bag, such as silver electrolysis, indium electrolysis, manganese electrodeposition, cobalt electrodeposition and the like, anode mud formed during electrolysis is settled in the diaphragm bag, and the diaphragm bag is required to be manually cleaned for reuse and collection of the anode mud; the cathode diaphragm method is to load the cathode plate into a cathode bag, such as nickel sulfide anode electrolysis, nickel electrowinning, coarse cobalt electrolysis, etc. The traditional diaphragm electrolysis technology has the defects that the workload of installing and discharging a diaphragm bag by a positive or negative plate is large, if diaphragm electrolysis of a diaphragm frame or a diaphragm frame is related to such as manganese, nickel, cobalt and the like, the workload is larger, and the assembly type diaphragm frame or the diaphragm frame can cause larger pole pitch error with the same name, so that the balance of the electrolysis process is seriously influenced, meanwhile, a cathode diaphragm method can also cause contact and even adhesion between the cathode and the diaphragm, thereby damaging the diaphragm, further, the diaphragm frame or the diaphragm frame has to be taken out from an electrolytic tank for replacement after production is stopped, and not only influencing the quality of a cathode product, but also influencing the productivity.
The diaphragm electrolysis which adopts a diaphragm to divide an electrolytic tank into an anode chamber and a cathode chamber is mainly used in chlor-alkali industry in the chemical industry, the electrolytic tank is formed by splicing and assembling a plurality of cathode chambers, anode chambers and cation exchange membranes, the splicing installation and the disassembly are complex, the polar plates and the cation exchange membranes are difficult to overhaul and replace, and the electrolyte is easy to leak; the cathode chamber and the anode chamber are sealed except for a product discharge port, and the difficulties of processing, operation and control are great; in the electrolysis process, saturated saline solution and NaOH dilute solution respectively enter from the bottoms of the anode chamber and the cathode chamber, the dilute saline solution and chlorine are discharged from the upper part of the anode chamber, and NaOH and hydrogen are discharged from the upper part of the cathode chamber without periodically filling out the anode plate and the cathode plate of the tank; anode mud is not generated in the electrolysis process, and an anode mud discharge port is not needed.
